There are presently no easily configurable, admin console controls to prevent students from opening multiple desks (desktops) in Chrome. We would welcome a change as it would prevent students from being off task and quickly concealing their tracks with a rapid, keystroke desk change. There is an open recommendation over in the Google Cloud community,

asking that the desk feature be made configurable and capable of being disabled. It seems like this would be ideal if as other browser settings, the feature can be enabled/disabled by OU.
The issue is going on two years old with very little movement or interest. If you would find this feature useful or if you would like to support those who feel that it would help, please make your way over to the link above and register your opinion. Thanks, all.
